Nikitich [7]

Answer:

The phylogenetic graph uses several types of variables to be formed, while other models use only one type of variable.

Explanation:

To create a phylogenetic chart, matrices with data on the studied species are used. These data are composed of morphological, chemical and / or genetic information that allow a detailed investigation about the ancestry of each species, in addition to allowing the correct grouping based on this ancestry and evolution.

A phylogenetic graph is different from other molecular models due to the number of data considered by it, since other models, such as the molecular clock, for example, only consider genetic based information.

However, the researcher does not show the study variables and, consequently, does not show any relationship between the variables and the research result. For this reason, we can state that based on this result, all results for experimental groups involving wing surgery would be invalid.
